Checkmk Development Tools
This repository includes scripts/tools for Checkmk developers.
- TBD: what should go here
- TBD: what shouldn't go here
Installation
While you can just clone and use the tools inside of course (they're just plain Python or Bash
scripts), the intended way to use it is via pip
or inside a virtual environment.
Install it locally using pip
:
[<PYTHON> -m] pip[3] install [--user] [--upgrade] checkmk-dev-tools
Contained tools
ci-artifacts
ci-artifacts
is a tool for accessing and triggering (currently Jenkins only) CI job builds and
making build artifacts available locally in an efficient way (i.e. avoiding unnessessary builds by
comparing certain constraints like job parameters and time of already available builds).
Formerly it was only used to make artifacts available which is the reason for the name and some
CLI desing desicions.
Usage
Run ci-artifacts --help
in general to get more details about the usage of the tool.
If no API key, username and URL to Jenkins is provided in ~/.config/jenkins_jobs/jenkins_jobs.ini
those parameters have to be specified explicitly.
This is a template of the jenkins_jobs.ini
file

Await result
Wait for an existing and specified build to finish. Nothing is downloaded.
ci-artifacts --log-level debug \
await-result checkmk/master/builders/build-cmk-distro-package:6066
The returned result is a JSON might look like
{"result": "SUCCESS", "artifacts": null}
Download
Wait for an existing and specified build to finish and download the artifacts.
The destination of the artifacts can be specified with the optional argument --out-dir
(defaults to out
) and is relative to the base directory (--base-dir
, defaults to current directory) used to fetch hashes of the downloaded artifacts.
The flag --no-remove-others
can be used to keep additional files in the download directory which were not part of the download. This is like a built-in garbage collection.
ci-artifacts --log-level debug \
download checkmk/master/builders/build-cmk-distro-package:6066 \
--base-dir ~/my-git-projects/checkmk/master \
--out-dir package_download \
--no-remove-others
The returned result is a JSON might look like
{"result": "SUCCESS", "artifacts": ["check-mk-enterprise-2.4.0-2024.10.31_0.jammy_amd64.deb"]}
Fetch
If there are no more constraints than a build has been completed successfully, fetch
downloads a given jobs artifact, just like with download
but for the latest build instead of a specified build number.
Pressing CTRL+C
while the script is running will ask for confirmation, default answer is no
and cancel the build.
ci-artifacts --log-level debug \
fetch checkmk/master/winagt-build
In contrast, this is what a more detailed call might look like
ci-artifacts --log-level debug \
fetch checkmk/master/winagt-build \
--params EDITION=raw,DISTRO="ubuntu-22.04",CUSTOM_GIT_REF=85fa488e0a32f6ea55d8875ab9c517bdc253a8e1 \
--params-no-check DISABLE_CACHE=false,CIPARAM_OVERRIDE_BUILD_NODE=fra001 \
--dependency-paths agents/wnx,agents/windows,packages/cmk-agent-ctl \
--time-constraints today \
--base-dir ~/my-git-projects/checkmk/master \
--out-dir package_download
--params <JOB-PARAMETERS>
Comma separated list of job-parameters used for identifying existing builds and
to start new ones.
--params-no-check <JOB-PARAMETERS>
Comma separated list of job-parameters used only to start a new build. These parameters are ignored during the search of an already existing build.
--time-constraints <SPECIFIER>
Check for build date constraints when looking for existing builds - currently
only today
is taken into account.
--dependency-paths <PATH,..>
Comma separated list of relative paths to files and directories checked for
differences when looking for existing builds.
--omit-new-build
Don't start new builds, even when no matching build could be found.
--force-new-build
Don't look for existing builds, always start a new build instead.
Request
Like fetch
but with the optional parameter --passive
which outputs the informations needed to trigger a build instead of triggering the build.
This is helpful in pipeline scripts to keep track of issuers of a build.
ci-artifacts --log-level debug \
request checkmk/master/winagt-build \
--params EDITION=raw,DISTRO="ubuntu-22.04",CUSTOM_GIT_REF=85fa488e0a32f6ea55d8875ab9c517bdc253a8e1 \
--params-no-check DISABLE_CACHE=false,CIPARAM_OVERRIDE_BUILD_NODE=fra001 \
--time-constraints today \
--base-dir ~/my-git-projects/checkmk/master \
--passive
{
"new_build":
{
"path": "checkmk/master/winagt-build",
"params":
{
"EDITION": "raw",
"DISTRO": "ubuntu-22.04",
"CUSTOM_GIT_REF": "85fa488e0a32f6ea55d8875ab9c517bdc253a8e1",
"DISABLE_CACHE": "false",
"CIPARAM_OVERRIDE_BUILD_NODE": "fra001"
}
}
}
Without the --passive
flag the build is triggered if no matching one is found. If a matching build with the specified parameters was found the returned JSON might look like
{
"existing":
{
"path": "checkmk/master/winagt-build",
"number": 6066,
"url": "https://JENKINS_URL.tld/job/checkmk/job/master/job/winagt-build/6066/",
"result": "SUCCESS",
"new_build": false
}
}
Validate
The validate
subcommand is a combination of several other commands. It requests, identifies a matching of triggers a new build while waiting for the build to complete. Nothing is downloaded. It has the same parameters as fetch
.
This subcommand can be used to trigger a remote build with custom parameters or check if an existing build with these parameters passed or not.
ci-artifacts --log-level debug \
validate checkmk/master/winagt-build \
--params EDITION=raw,DISTRO="ubuntu-22.04",CUSTOM_GIT_REF=85fa488e0a32f6ea55d8875ab9c517bdc253a8e1 \
--params-no-check DISABLE_CACHE=false,CIPARAM_OVERRIDE_BUILD_NODE=fra001 \
--time-constraints today
{"result": "SUCCESS", "artifacts": []}
Todo
Development & Contribution
Setup
For active development you need to have poetry
and pre-commit
installed
python3 -m pip install --upgrade --user poetry pre-commit
git clone ssh://review.lan.tribe29.com:29418/checkmk_dev_tools
cd checkmk_dev_tools
pre-commit install
poetry env use ~/.pyenv/versions/3.10.4/bin/python3
poetry install
poetry self add poetry-bumpversion
Workflow
- (once and only for publishing to PyPi) Get token on PyPi.org
- (once and only for publishing to PyPi)
poetry config pypi-token.pypi pypi-<LONG-STRING>
(will write to ~/.config/pypoetry/auth.toml
) - modify and check commits via
pre-commit run --all-files
- after work is done locally:
- adapt version in
pyproject.toml
with
poetry version [patch, minor, major] [--dry-run]
- may update dependencies before/with a new release
poetry lock
- build and check package locally
poetry build && \
poetry run twine check dist/* &&
python3 -m pip uninstall -y checkmk_dev_tools && \
python3 -m pip install --user dist/checkmk_dev_tools-$(grep -E "^version.?=" pyproject.toml | cut -d '"' -f 2)-py3-none-any.whl
- commit, push, review and merge the changes, see
checkmk_dev_tools/+/88632/
git add ...
git commit -m "cmk-dev-tools: bump version, update dependencies"
- publish new package version
poetry publish --build [--repository checkmk_dev_tools]
git tag -a v<VERSION> <MERGE_COMMIT> -m "v<VERSION>"
git push --tags
